Inspection of Cylinder Condition:

Through scavenging port

Wear condition of Piston ring, Cylinder Liner.

Check of Alpha Lubrication System:

Operation condition, Alarm log/record.

Optimal adjustment and feed rate setting.

General inspection according to actual operating condition:

At the inspection before dry-dock (3 months prior),

in addition to the above items, HPS driving chain,

Exhaust Cam (for ME-B) and each bearing will be

inspected visually.

General Inspection of M/E

Alarm List, Event Log

5

Function test


Step 1: Check Alarm List and Event Log.

Check the operation of equipment by MOP function test.

Confirmation of M/E operating condition based on the alarm event log.

Detailed investigation of the alarm records.

Confirmation of equipment working condition, and check the feedback

sensor’s signal / current by MOP function test.

Accumulator Accumulator

Pressure check is recommended every 6 months.

6


Step 2: Accumulator ( for HCU & HPS )

Check the Nitrogen gas pressure.

Instruction and Supervision for re-charging Nitrogen gas.

Check and measure the Nitrogen gas pressure in accumulator.

If the pressure is low, re-charging will be instructed.

※Nitrogen gas is to be re-charged by ship’s crew.

Nitrogen gas bottle is to be provided by the vessel.

7


Step 3: Check for internal oil leakage at HCU, HPS.

Hydraulic oil pressure test by Start-up pump.

Hydraulic oil pressure is measured while operating Start-up

pump, and the operation condition and abnormalities

including wear on each valve is to be checked.

EICU Engine Interface Control Unit

ECU Engine Control Unit

CCU Cylinder Control Unit

ACU Auxiliary Control Unit

SCU Scavenging Control Unit

(for EGB, VTA)

MOP Main Operating Panel

Step 4: System View I/O Test, Check for Network Status.

Back-up of ME-ECS parameter file.

Check for any abnormalities on each PCB and network

connection which is the structure of the M/E control

system.

After no abnormality is confirmed on the system,

ME ECS parameter file will be backed-up, and it will

be stored in MES as the latest data file.

9


Step 5: Inspection for the operation condition of

Fine filter for hydraulic oil.

• Check of differential pressure between hydraulic oil inlet and outlet.

• Function Check of back flushing.

• Explanation of maintenance and cleaning of elements.

In order to keep good condition of each device on M/E, regular maintenance is recommended.

simulator at MES Tamano.

Option : Instruction for ship staff / engineers

Simple Training on board for ME engine.

Increased knowledge and technical skill of crew = “SAFE OPERATION”

Early detection and early resolution of engine trouble

Explanation of MOP functions

Explanation of each equipment

and sensor signal

Engine side / Arrangement of

each equipment and sensor

How to respond at the time of

alarm and trouble
